I hope i will never have to replace//install this device again, it works fine and looks clean with easy power/usb power in the back which is nice and the cables are quite thick compared to other 9v power cables i have, i haven't noticed any noise yet which is nice though i haven't had it long yet.
but man those screws...
I realize i have quite big hands but i consider myself handy/nimble enough yet it took me more then an hour to secure 4 screws and it still slightly wiggles...
depending on your board model you first have to remove the center legs to even be able to reach the two screws that hold the power mod, and even then the screws are so tiny and close to it that its very hard to apply them, then you have to put the legs back where you have to secure the screw upside down in a hard to reach spot..
